The nifty app CamFind has come a long way with its artificial intelligence (AI). It uses image recognition to identify an object when you point your smartphone camera at it.
However, back in 2015, its algorithms were less advanced: The app mostly used contract workers in the Philippines to quickly type what they saw through a user’s phone camera, CamFind’s cofounder confirmed to me recently.
You would not have guessed that from a press release it put out that year which touted industry-leading “deep learning technology,” but did not mention any human labelers.

The practice of hiding human input in AI systems still remains an open secret among those who work in machine learning and AI. A 2019 analysis of tech start-ups in Europe by London-based MMC Ventures even found that 40 percent of purported AI start-ups showed no evidence of actually using artificial intelligence in their products.
This so-called “AI washing” should not be surprising. Global investment into AI companies has steadily risen over the past decade and more than doubled in the past year, according to market intelligence firm PitchBook.
Calling your start-up an “AI company” can lead to a funding premium of as much as 50 percent compared with other software companies, according to the MMC Ventures analysis.
Yet ignoring the workers who power these systems is leading to unfair labor practices and skewing the public’s understanding of how machine learning actually works.
In Silicon Valley, many start-ups have succeeded by following the “fake it ’til you make it” mantra. For AI companies, hiring people to prop up algorithms can become a stopgap, which on occasion becomes permanent.
Humans have been discovered secretly transcribing receipts, setting up calendar appointments or carrying out bookkeeping services on behalf of “AI systems” that got all the credit.
In 2019, a whistle-blower lawsuit against a British firm claimed customers paid for AI software that analyzed social media while staff members were doing that work instead.
There is a reason this happens so often. Building AI systems requires many hours of humans training algorithms, and some companies have fallen into the gray area between training and operating.
A common explanation is that human workers are providing “validation” or “oversight” to algorithms, like a quality-control check.
However, in some cases, these workers are doing more cognitively intensive tasks because the algorithms they oversee do not work well enough on their own. That can bolster unrealistic expectations about what AI can do.
“It’s part of this quixotic dream of super-intelligence,” says Ian Hogarth, an angel investor, visiting professor at University College London and coauthor of an annual State of AI report that was released on Tuesday.
For the hidden workers, working conditions can also be “anti-human,” he says.
That can lead to inequalities and poor AI performance.
For instance, Cathy O’Neil has noted that Facebook Inc’s machine-learning algorithms do not work well enough in stopping harmful content. (I agree.) The company could double its 15,000 content moderators, as suggested by a recent academic study.
However, Facebook could also bring its existing moderators out of the shadows.
The contract workers are required to sign strict non-disclosure agreements and are not allowed to talk about their work with friends and family, says Cori Crider, the founder of tech advocacy group Foxglove Legal, which has helped several former moderators take legal action against Facebook over allegations of psychological damage.
Facebook has said content reviewers could take breaks when they needed and were not pressured to make hasty decisions.
Moderation work is mentally and emotionally exhausting, and Crider says contractors are “optimized to within an inch of their lives” with an array of targets to hit.
Keeping these workers hidden only exacerbates the problem.
A similar issue affects Amazon.com Inc’s MTurk platform, which posts small tasks for freelancers.
In their book Ghost Workers, Microsoft Corp researchers Mary Gray and Siddharth Suri say these freelancers are part of an invisible workforce labeling, editing and sorting much of what we see on the Internet.
AI does not work without these “humans in the loop,” they say, yet people are largely undervalued.
A recent paper from academics at Princeton University and Cornell University called out data-labeling companies like Scale AI Inc and Sama Inc who pay workers in Southeast Asia and sub-Saharan Africa US$8 a day. Sure, that is a living wage in those regions, but long-term it also perpetuates income inequality.
A spokeswoman for Sama said the company has helped more than 55,000 people lift themselves out of poverty, and that higher local wages could negatively impact local markets, leading to higher costs for food and housing.
Scale AI did not respond to a request for comment.
“Microwork comes with no rights, security, or routine and pays a pittance — just enough to keep a person alive yet socially paralyzed,” writes Phil Jones, a researcher for the British employment think tank Autonomy, adding that it is disingenuous to paint such work as beneficial to a person’s skills.
Data labeling is so monotonous that Finland has outsourced it to prisoners.
Improving the employment status of these workers would make their lives better and also improve AI’s development, since feeding algorithms with inconsistent data can hurt future performance.
Crider says Facebook needs to make its content moderators full-time staff if it really wants to fix its content problems (most of them work for agencies like Accenture PLC).
The Princeton and Cornell researchers say labelers need a more visible role in the development of AI and more equitable pay.
One glimmer in the darkness: Freelancers who do microtasks on Amazon’s MTurk platform have recently been holding worker forums to approach Amazon on issues like rejected work, according to one of their representatives.
They are not creating a union per se, but their work is a unique attempt at organizing, giving AI’s ghost workers a voice they have not had until now. Here is hoping the idea catches on more broadly.

China’s chip industry is growing faster than anywhere else in the world, after US sanctions on local champions — from Huawei Technologies Co (華為) to Hikvision Digital Technology Co (海康威視) — spurred appetite for homegrown components. Nineteen of the world’s 20 fastest-growing chip industry firms over the past four quarters, on average, hail from the world’s No. 2 economy, data compiled by Bloomberg showed. That compared with just eight firms at the same point last year. Revenue at China-based suppliers of design software, processors and gear vital to chipmaking is increasing at several times the pace of global leaders Taiwan Semiconductor Manufacturing Co
Had Audrey Hepburn and Gregory Peck hopped on an electric scooter rather than a Vespa in the classic film Roman Holiday, their spin around the Eternal City might have ended in tears. The number of crashes and near-misses involving the two-wheelers has prompted Rome authorities to impose some order on a booming rental market that began two years ago. The havoc came to a head earlier this month when two US tourists attempted a night-time drive down the Spanish Steps, causing more than 25,000 euros (US$26,392) worth of damage to the 18th-century monument. Caught on security footage, the couple in their late 20s
POSITIVE SIGNS: GlobalWafers has continued to sign long-term supply agreements, most of which exceed 2028, and aside from one factory, it is running at full capacity GlobalWafers Co (環球晶圓), the world’s third-largest silicon wafer maker, yesterday said that Samsung Electronics Co and most of its customers have not scaled back on orders, or delayed shipments, even though consumer spending has shifted away from smartphones and notebook computers due to mounting inflation pressures. Rising inflation has altered consumers’ spending habits, dampening sales of consumer electronics, the Hsinchu-based company said. However, customers all honored their supply agreements by adjusting their product mix and shifting to applications that are still reporting robust growth, it said. Aside from one 6-inch factory, GlobalWafers’ 15 factories around the world are running at 100 percent
Nearly a quarter of European companies in China are considering shifting their investments out of the country as COVID-19 outbreaks and lockdowns dim the outlook for the world’s second-largest economy, a survey showed. About 23 percent of the businesses that responded to the survey are thinking of moving their current or planned investments away from China, a report released yesterday by the EU Chamber of Commerce in China said. The survey was conducted at the end of April, when Shanghai was still in shut down and restrictions in places like Jilin Province disrupted business activity. The number of European firms reassessing
